JS Output Challenges - Snippet Practice

#1Promise Resolve & Reject

const promise = new Promise((resolve , reject) => {
    resolve(10);
    reject(20);
    console.log("here");
})

promise.then((value) => {
    console.log(value);
})

What will be the output?

#2Promise Reject with Then Handlers

const promise = new Promise((resolve , reject) => {
    reject(20);
    console.log("here");
})

promise.then(
  (value) => {
    console.log("ok");
  },
  (value) => {
    console.log(value);
  }
);

What will be the output?

#3Array Equality Comparison

let a = [];
let b = [];

console.log(a == b);
console.log(a === b);

What will be the output?

#4Temporal Dead Zone with Let

let temp = 'outer value';
if (true) {
  console.log(temp);
  let temp = 'inner value'; 
  console.log(temp);
}
console.log(temp);

What will be the output?

#5Let and Var Redeclaration

let temp = 'outer value';
if (true) {
  console.log(temp);
  var temp = 'inner value';
  console.log(temp);
}
console.log(temp);

What will be the output?

#6Var Hoisting in Block

var temp = 'outer value';
if (true) {
  console.log(temp);
  var temp = 'inner value'; 
  console.log(temp);
}
console.log(temp);

What will be the output?
